That is, each of the first through fifth lens elements is asingle and non-cemented lens element, and every two lens elementsadjacent to each other are not cemented, and there is a space betweenthe two lens elements. Moreover, the manufacturing process of thecemented lenses is more complex than the non-cemented lenses. In otherwords, of the first lens element, the second lens element, the thirdlens element, the fourth lens element and the fifth lens element of theoptical photographing lens assembly, there is a space in a paraxialregion between every pair of lens elements that are adjacent to eachother. In particular, a second surface of one lens element and a firstsurface of the following lens element need to have accurate curvature toensure these two lens elements will be highly cemented.
